[0009] The main supporting post (2) is a rod body and the top end thereof is in a flat shape with a hole in the center; a bolt (22) sleeved by a spring (23) extends through the main supporting post (2) and the position supporting board (111), then threaded onto a nut (24); the resistance from the spring (23) enables the position supporting board (111) to maintain a tight pivotal joint with the top end of the main supporting post (2); the bottom clamping frame (7) comprises an horizontal supporting rod (71) and a sliding seat (72); on the sides and the top planes along the axle of the horizontal supporting rod (71) respectively, a plurality of adjusting fixing holes (711) and concave holes (714) are disposed; the two end portions separately have a lateral bent portion (712) bent at a proper angle; each lateral bent portion (712) is disposed with a plurality of fixing holes (713).

[0010] The sliding seat (72) is inserted onto the peripheral side of the horizontal supporting rod (71) and the inner top plane thereof is disposed with at least a steel bead (726) to be fitly inserted into the concave hole (714) on the top plane of the said horizontal supporting rod (71) for positioning; the outer peripheral rim of the said sliding seat (72) extend to form two corresponding branch portions (721); a retaining tab (722) is pivotally jointed onto the two branch portion (721); the said retaining tab (722) has a push tab (724) and at least a bent forked hook (723) respectively protruding outwardly; the exterior side of the sliding seat (72) has a plurality of lateral holes (725) located on the pivotally rotating path of the said forked hook (723); the retaining tab (722) has a spring inside to enable the forked hook (723) to be inserted into the lateral holes (725) in an initial state; pushing the push tab (724), the forked hook (723) is retracted from the lateral hole (725); the other lateral side of the sliding seat (72) is connected to a clamping jacket (73), the said clamping jacket (73) consists of two opposite curved pieces to form a clamping hole (731); the moveable end enables a bolt (732) to extend through and be tightly screwed onto a forced rotating button (733) thereby narrowing the clamping hole (731) so as to clamp onto the bottom end of the main supporting post (2).

[0011] When in use, a plurality of fixed clamping ring (74) with an opening is clamped onto the handle bar (5) of the bicycle; two opening end portions of the fixed clamping ring (74) are disposed with an outwardly extended portion (741); the extended portion (741) has fixing holes to allow bolts to extend through and to join the fixing hole (713) of the lateral bent portion (712) to thereby enable the horizontal supporting rod (71) to be positioned on the bicycle's handle bar (5); the sliding seat (72) slides along the horizontal supporting rod (71) to a proper position to enable the lateral hole (725) thereof to coincide with the adjusting position hole (711) on the horizontal supporting rod (71), whereas the forked hook (723) of the retaining tab (722) reaches into the lateral hole (725) and inserts into the adjusting position hole (711) to enable the sliding seat (72) to be positioned at a proper location on the horizontal supporting rod (71); the bottom end of the main supporting post (2) extends into the clamping hole (731) of the clamping jacket (73), fastening a bolt (732) to a forced rotating button (733) for positioning, the top end of the main supporting post (2) is pivotally jointed to the position supporting board (111) of the fixed arm (11) to enable the clamp holder (1) to form a pitched angle, such that the umbrella handle grip (6) inserts between the bent portion (114) or the clamping jacket (115) and the clamping position or the clamping jacket (123) of the moveable clamping arm (12); flipping the press button (1311) outwardly disengages the eccentric disk (131) from the fixed arm (11) and the moveable clamping arm (12) and facilitates an easy rotation of the adjusting bolt (13) to clamp the said umbrella handle grip (6); pressing the press button (1311) inwardly against the eccentric disk (131) again forces the tightening of the fixed arm (11) and the moveable clamping arm (12) so as to accomplish the most adequate efficiency of clamping the umbrella handle grip (6).

[0012] The abovementioned structure of the present invention uses a sliding seat (72) that slides on the horizontal supporting rod (71) and uses forked hook (723) thereof to extend through the lateral hole (725) to be retained on the adjusting position hole (711) of the horizontal supporting rod (71), therefore to enable the umbrella to be adjustably positioned depending on the need (e.g., when wind, rain, or sun ray shifts its direction) at any time to achieve the best sheltering effect).

[0013] The abovementioned structure of the present invention in addition to be disposed on a bicycle to hold an umbrella, it can also be disposed on other or related objects (e.g., baby carriages) that have a need for an application of automatically clamp-holding an umbrella or similar items.
